This helps improve response times for both queries and create, retrieve, update, and delete (CRUD) operations, and it also improves concurrency.
这有助于改进查询以及创建、检索、更新和删除(CRUD)操作的响应时间，还会改进并发性。

In implementing systems with high concurrency requirements we can devise finer grained locking strategies based on the access requirements of the operations, hence reducing contention for resources.
在实现具有高并发性要求的系统时，我们可以基于操作的要求采用更细粒度的锁定策略，从而减少资源争用。

In addition to the other concurrency utilities for locking and atomic operations, expect to use these classes regularly.
